Abstract: A weeping wall has a wall body, a flowable substance inlet, at least one mobile deflector, and a flowable substance outlet. The wall body has a flow surface with a magnetic material layer extending along at least a portion thereof. The flowable substance inlet is at an upper end of the flow surface, with a flowable substance continuously flowing therefrom and downwardly onto the flow surface. The mobile deflector is movably engaged to the flow surface and projects therefrom. The mobile deflector includes a magnet and is magnetically held in place on the flow surface to be selectively movable relative to the flow surface to modify a flow path of the flowable substance on the flow surface. The flowable substance outlet is defined at a lower end of the flow surface with the flowable substance flowing continuously therein after running down onto the flow surface.

Abstract: A weeping wall for receiving a continuous flow of a flowable substance. The weeping wall comprises: a wall body including a substantially vertical wall section having a flow surface; a flowable substance inlet defined at an upper end of the substantially vertical wall section, with the flowable substance continuously flowing therefrom and downwardly onto the flow surface; at least one mobile deflector movably engaged to the flow surface and projecting therefrom, the at least one mobile deflector being selectively movable relative to the flow surface to modify the flow path of the flowable substance on the flow surface; and a flowable substance outlet defined at a lower end of the substantially vertical wall section with the flowable substance flowing continuously therein after running down onto the flow surface.
